* jokerjack:

has anyone been able to setup the above video card with a pair for use
of SLI on a HP xw6400, this supports SLI

No, it doesn't. The xw6400 is a dual XEON 5000/5100/5300 series machine
which uses the intel 5000X chipset. This chipset doesn't support SLI at
all. You can use two gfx cards in non-SLI config, though.

but when i have both cards in
the PC it wont boot up as it beeps... the PC isn't getting past POST.

Does the machine work with a single card? If yes, have you tried both cards?

Also does anyone know if i need the HP bridge or does anyone work, ie
ASUS.

The SLI brigdes are basically all the same except regarding the length.
You of course need a bridge that has sufficient cable length, but since
the xw6400 doesn't support SLI this point is mood.

BTW: it's a bit strange to put a cheap overclocker card in a
not-so-cheap workstation. Probably not the best combination.
